IMPROVEMENT IN FLOOK-DUSTER.

TO ALL 'WI-IOM IT MAY CONCERN:

Be it known that I, h/IILES WATERHOUSE, of Passaic, in the county of Pussaie, and State of New Jersey, have invented a new and useful Machine for the Purpose of Separating, Dusting, or Cleaning Woollen Flocks, or other filamentous substances; and I hereby declare the following to be a full and exact description thereof, reference being had to the annexed drawings, making part of this specification, in which- Figure I is an end view of the casing or outside framework of the machine.

Figure II is a transverse sectional view.

Figure III is a longitudinal view, showing the several parts in section.

Like lctters denote like parts in the several figures;

The casing or framework aeonsists of a rectangular box, which is covered by the top or lidb, to which is secured the hopper or inlet 0. The shaft (1 has its hearings in the ends of the case a, and receives rotary motion through the pulley it, fast upon the end of one of its journals. Around the shaft :1, in the'form of a. screw or helix, are placed the beater-blades and brushes d d d, 8L0. Beneath the brush-shaft d, and concentric there with, is the semi-cylindrical wire screen e, which is fastened to the framework, and supported at proper distances by the inverted bridge-piccesg gg g, the ends of which are sustained by the two longitudinal pieces gg. The curved opening f'is for the discharge of the flock or filamentous matters, after having undergone the separating or cleansing process.

Rotary motion being communicated to the shaft d through the pulley It in the proper direction, and the 'flocks to be operated upon fed in by the hopper c, a violent tossing, heating, or trituration of the flocks will be accomplished by the heaters and brushes d'd' d, and at thosamc time a forward movement towards the outlet fwill boprodueed regularly and continuously. The action of the brushes and heaters is to force the flocks alternately against and sweep them from the surface of the screen 0, and at the same time to carry them forward, in consequence of their spiral arrangement, continuously towards the outlet or aperture of discharge In this way the small and ralueless particles of wool or foreign matters are separated from themore valuable. and forced through the semi-cylimlrical screen or sieve, and retained in the enclosed space or receptacle below the inverted bridge-pieces. I

v I do not claim broadly the use of brushes or boaters in cleaning or separating flocks or other filamentous 'material; neither do I claim for such purpose a semi-cylindrical screen, as such has been used before; but

I do claim the rotating brush-cylinder d, with its spirally-arranged brushes and heaters d d (2, when combined together, and with the screen c and the openings 0 and f, in the manner and for the purposes shown and described.
